30Cr2Ni2Mo transmission shaft
The 30Cr2Ni2Mo transmission shaft is a high-strength alloy metal factor extensively used in heavy-duty and precision force systems. Known as the Chinese equal of 30CrNiMo8 metal (DIN standard), this alloy presents an fantastic stability of strength, toughness, and hardenability — making it best for transmission shafts, pressure shafts, and output shaft transmission structures below complicated running conditions.
Description
1. Material Properties of 30Cr2Ni2Mo Steel
The 30Cr2Ni2Mo alloy belongs to the category of alloy structural steels, designed to face up to excessive torque, impact, and fatigue stress.
Its most reliable mechanical overall performance comes from its alloying factors — Chromium (Cr), Nickel (Ni), and Molybdenum (Mo) — which collectively decorate each electricity and warmth remedy response.
Key mechanical homes (after quenching and tempering):
Tensile strength: one thousand – 1200 MPa
Yield strength: 850 – one thousand MPa
Impact longevity (AK): ≥40 J (at 20°C)
Fracture longevity (KIC): ≥50 MPa·m¹/²
Hardenability depth: ≥100 mm
2. Heat Treatment and Processing Technology
Proper warmness cure is integral for optimizing the mechanical stability of the 30Cr2Ni2Mo transmission power shaft.
Quenching: Heating to 850–880°C observed via oil or water cooling to shape martensite, organising the high-strength foundation.
Tempering: Heating between 540–660°C to stability power and toughness. Lower temperatures grant greater strength, whilst greater temperatures enhance ductility and shock resistance.
Depending on provider stipulations — such as excessive load, vibration, or temperature variant — the warmth cure manner can be finely adjusted to acquire dependable performance.
